got 2 new books for xmas and have now started using them
Seasearch Observers Guide to Marine Life of Britain and Ireland-Chris Wood
and
Seasearch Guide to Sea Anemones and Corals of Britain and Ireland-Chris Wood
Superb books the photos are fabulous and I like the way they give the common names for so many things (not a hope in hell of ever remembering latin ones). Names like crater sponge, shredded carrot sponge....
They are very user friendly and laid out very well so that you can easily find the info you want.
Although i shall probably continue to use the others I have, as no single book covers everything, these will definatley get a lot of use.
